OBJECTIVE: To investigate the association between adverse surgical outcomes following bariatric surgery and proxy measures of vitamin D (VitD) status (season and latitude) in the Nationwide Inpatient Sample (NIS). BACKGROUND: Obesity is an independent risk factor for VitD deficiency (25(OH)D < 20 ng ml(-1)). VitD deficiency compounds the chronic inflammation of obesity, increasing the risk of adverse outcomes following bariatric surgery. Epidemiology has long used season and latitude as proxies for group VitD, as VitD status is largely determined by sun exposure, which is greatest during summer and at the Equator...

BACKGROUND: With over 110,000 bariatric operations performed in the United States annually, it is important to understand the biochemical abnormalities causing endocrine dysfunction associated with these procedures. Here we compare 2 malabsorptive procedures, duodenal switch and Roux-en-Y gastric bypass, to determine the role malabsorption plays in secondary hyperparathyroidism in this population. METHODS: Data from all super-obese patients undergoing duodenal switch or Roux-en-Y gastric bypass between August 2002 and October 2005 were prospectively collected...

RATIONALE: Clinical control is difficult to achieve in obese patients with asthma. Bariatric surgery has been recommended for weight-loss and to improve asthma control; however, the benefits of nonsurgical interventions have been poorly investigated. OBJECTIVE: To examine the effect of exercise training in a weight-loss program on asthma control, quality of life, inflammatory biomarkers and lung function. METHODS: Fifty-five obese patients with asthma were randomly assigned to either a weight-loss program + exercise (WL+E group, n=28) or a weight-loss program + sham (WL+S group, n=27) group, where the weight-loss program included nutrition (caloric restriction) and psychological therapies...

BACKGROUND & AIMS: Obesity is a worldwide health problem. Bariatric surgery (BS) is becoming one of the most commonly used methods for fighting obesity and its associated comorbidities. However, current BS techniques can be associated with early or late complications that may require nutritional support. The aim of this retrospective observational study was to determine the indications and outcomes for patients on Home parenteral nutrition (HPN) due to post-bariatric surgery complications...

PURPOSE OF REVIEW: In the context of the worldwide obesity epidemic, bariatric surgery is the only therapy associated with a sustainable weight loss and to midterm prevention of obesity-related complications. However, nutritional and behavioral multidisciplinary medical preparation, as well as long-term postoperative nutritional follow-up, is strongly advised to avoid postoperative surgical, nutritional, or psychiatric complications. RECENT FINDINGS: Due to a long history of restrictive diets and large body weight fluctuations, preoperative nutritional assessment and correction of vitamin and trace elements deficiencies are mandatory...

BACKGROUND AND AIMS: Small intestinal bacterial overgrowth (SIBO) has been described in obese patients. The aim of this study was to prospectively evaluate the prevalence and consequences of SIBO in obese patients before and after bariatric surgery. PATIENTS AND METHODS: From October 2001 to July 2009, in obese patients referred for bariatric surgery (BMI >40 kg/m(2) or >35 in association with comorbidities), a glucose hydrogen (H2) breath test (BT) was performed before and/or after either Roux-en-Y gastric bypass (RYGBP) or adjustable gastric banding (AGB) to assess the presence of SIBO...

While vitamin D deficiency is prevalent among obese individuals, its cause is poorly understood. Few studies have measured vitamin D concentrations in adipose of obese (OB) subjects, and none have included normal weight controls (C). The goal of this study was to investigate whether the relationship between body composition, serum 25-hydroxyvitamin D (25OHD), vitamin D in subcutaneous (SQ) and omental (OM) adipose and total adipose stores of vitamin D differ among OB and C. Obese women undergoing bariatric surgery and normal weight women undergoing abdominal surgery for benign gynecologic conditions were enrolled...

BACKGROUND: In a recent study of patients using vitamin K antagonists, those with low free thyroxin (FT4) levels within the normal range had a 3- to 5-fold increased risk of major bleeding. We tested the hypothesis that low levels of preoperative FT4 within the reference range are associated with an increased risk of major bleeding during and after bariatric surgery. METHODS: The charts of 2,872 consecutive patients undergoing bariatric surgery were retrospectively screened for bleeding episodes...

Bariatric surgery is most commonly carried out in women of childbearing age. Whilst fertility rates are improved, pregnancy following bariatric surgery poses several challenges. Whilst rates of many adverse maternal and foetal outcomes in obese women are reduced after bariatric surgery, pregnancy is best avoided for 12-24 months to reduce the potential risk of intrauterine growth retardation. Dumping syndromes are common after bariatric surgery and can present diagnostic and therapeutic challenges in pregnancy...

Bariatric surgery is well-recognized for its effects on health, beyond weight-loss. It underwent a revolution recently with the growing performance of laparoscopic procedures, leading to enhanced recovery and a reduction in procedural risk. However, surgical complications, although rare, do develop. It is important to recognize the complications, and ideally prevent them from happening. This article reviews the risks of the four most commonly performed bariatric procedures, with an emphasis on technique and management in the intraoperative and postoperative period...

BACKGROUND: The expansion of the obesity epidemic is accompanied with an increase in bariatric procedures, in particular in women of reproductive age. The weight loss induced by the surgery is believed to reverse the negative impact of overweight and obesity on female reproduction, however, research is limited to in particular retrospective cohort studies and a growing number of small case-series and case-(control) studies. METHODS/DESIGN: AURORA is a multicenter prospective cohort study...

BACKGROUND: Vitamin supplementation in bariatric aftercare is essential to prevent nutrient deficiencies; however, rates of vitamin adherence have been as low as 30 % 6 months post-surgery. Preliminary literature suggests non-adherence to prescribed treatments can be linked to demographic and psychological factors. We aimed to determine the relationship between these factors to vitamin adherence in post-bariatric surgery patients. METHODS: A total of 92 bariatric patients were assessed 6 months post-surgery...

Severe obesity (body mass index ≥40 kg/m(2)) is a chronic disease that is associated with significantly increased risk of serious and chronic health problems as well as impaired quality of life. For those with severe obesity, bariatric surgery is the most effective treatment for significant and long-term weight loss and resolution of comorbid medical conditions, particularly diabetes. Long-term success is thought to depend to some degree on the patient's ability to adhere to a complex set of behaviors, including regular attendance at follow up appointments and following stringent dietary, exercise, and vitamin recommendations...

BACKGROUND: After Roux-en-Y gastric bypass, calcium and vitamin D deficiencies are frequently reported. In the presence of adequate vitamin D levels, calcium deficiency is caused by a lower efficacy of the intestinal calcium transport. OBJECTIVE: To investigate whether the use of a simple clinical score quantifying bowel habits (fecal score [FS]) correlates with the degree of secondary hyperparathyroidism that arises to compensate for calcium deficiency postsurgery...

As discussed in Part 1, obesity is now a global epidemic affecting a significant and rapidly increasing number of adults, adolescents, and children. As the incidence of obesity has increased, so has the use of bariatric surgery to treat it. A growing number of recently published studies have reported that, despite calcium and vitamin D supplementation, the most frequently performed types of bariatric surgery, the Roux-en-Y gastric bypass (RYGB) and the sleeve gastrectomy (SG), cause significant, ongoing bone loss...
